Say that you'd rather just see her be a baby.

"That's a but too much for me." You say. "Why don't you just show me what it's like when you are a baby."

She seems disappointed but agrees. "Okay."

She starts undressing. Stripping down to her diaper. As you stare at her body, she picks up the purple onesie and hands it to you. "I'm just a baby. You have to dress me."

You examine the garment for a moment to figure out how it goes on before holding it out for her to put her arms through and then pulling it down over her head, the fabric stretching across her breasts. Finally, you fasten the poppers at her crotch.

Stepping back, you have to admit, she does look cute. She looks at you expectantly, clearly if she's the baby you're going to have to take the lead here.

You pick up one of the pacifiers and place it in her mouth. She begins sucking on it immediately. You can see the edges of a contented smile around the shield.
